To provide a wage or free boat tickets would cost an absolute fortune. There are hundreds of us. You also would get some who came across then reneged, and it would add an enormous amount of work to TTMA team who already work outrageous hours.
Maybe a free raffle when you hand in your signed warrant card, with free flights/ boat tickets etc for the next year... maybe prizes donated by the big TT sponsors, and people like IOMSPC/ airlines/ Manx Radio etc etc.
Even a sandwich and a cup of tea each would be a lot of money, but the burger man at the bottom of Bray gives a very generous discount on all food and drinks to working marshals... others might too.
Any other ideas?
